5 Claims. (CL' 229-34) This invention relates to an improved carton formed from cardboard or other suitable material.

One of the objects of the invention is to pro- 5 vide an improved carton formed from cardboard or other suitable material.

Another object of the invention is to provide a novel display carton having improved means for securing the cover portion in locked position.

10 Other objects of the invention will be apparent from the description and claims which follow. Reference is now had to the drawing in which similar characters of reference are used to designate similar elements.

Figure l is a plan view of the improved carton blank for forming the carton of the present invention.

Figure'2 is a perspective view of the formed carton showing the cover in closed position. Figure 3 is a perspective view of the formed carton showing the cover in display position.

The carton blank illustrated in Figure 1 is formed of cardboardor other suitable material, cut and scored as shown, and comprises a bot- 25 tom l, side walls 2, rear wall 3 and cover 4.

Flaps 5 are formed integral with side walls 2 at the outer edges thereof and preferably extend the full length of side walls 2. Flaps 6 are formed integral with side walls 2 at their rear- -ward ends, one of the flaps 6 being provided with a tongue 1 andthe other of the flaps being provided with a slit 8.

In forming the carton, side walls 2 and rearwall 3 are folded at a right angle to bottom I 85- and the flaps 6 are folded one against the other and against the outer face of rear wall 3 with their respective tongue and slit interlocked thus securing the side walls 2 and rear wall 3 in relative position. v 40 The front wall of the formed carton comprises a batten 9 formed integral with each of the side walls at their forward edges and flap Ill formed integral with bottom I. Battens 9 are folded at a right angle to sides 2 and are each provided 4 with a tongue portion ll of relatively less height and extensible adjacent bottom t. Flap I0 is of a height substantially equal to the height of the tongue portions of the several battens and is tapered inwardly at its side edges, as at I2, 60 to provide a reduced outer edge l3 provided with a tongue l4 foldable between the battens 9. Tongue I4 is folded over and against tongue portions II and is secured by the insertion of 7 locking tabs l5 within slots I6 provided in score line ll.

It will be seen that in theformatlon of the front wall, just described, there is provided a strong reenforced wall partially cut away at its edge adjacent the cover for the display of the product contained within the carton. 5

Cover flap I8 is formed integral with cover 4 and is separated from cover 4 by score line I9. Flap I 8 is provided, at its outer edge, with I tongue 20 cut at its end edges to provide locking tabs 2| registrable with slits 22 in battens 9. 10

The carton is closed by folding flaps 5 at a right angle to sides 2, the cover 4 over and against the flaps 5 and the flap l8 over and against battens 8. The tongue 20 is inserted within front wall It) and the cover secured in locked position by tabs 2| interfitted within slits 22.

As a further display feature, cover 4 may be scored inwardly from its side edges, as at 23 and 24, and arcuately cut on line 25 in a manner to connect the adjacent ends of score lines 23 and 24 thus dividing cover 4 into panels 26 and 21. When it is desired to use, the carton for display purposes, panel is folded on score lines 23 and 24 over and against panel 21 and the 25 cover flap I8 is inserted within the carton adjacent the inner surface of rear wall 3. As shown in Figure 3, the rearward end edges 28 of flaps 5 serve to engage the folded panel 26 and thus coact with flaps 5 to maintain rear wall 3 in 30 relative folded position and the panels of cover 4 in an upright position.

The dimensional designation, such as, for example, the term fheight" as used in this specification and in the claims which follow, will be understood to denote dimensions of the respective parts as they appear in the formed carton shown in Figures 2 and 3, or in the blank shown in Figure 1, and will be clear from the context of this specification. 40
